The Telecom Spot Expert Review
If your team lives on calls but hates being chained to a desk, the Poly Savi 8420 is a game-changer. The DECT 1920-1930 MHz technology gives you true freedom—walk to the printer, grab coffee, or step into another room without losing connection. Stereo sound with active noise cancellation blocks out open-office chatter so you hear every word and your callers hear only you, thanks to the close-conversation-limiting microphone.
The universal base is the real hero here: one clean unit connects your PC (USB-A or USB-C), desk phone, and mobile phone simultaneously. A quick press of the Microsoft Teams button jumps you into meetings. Color display and simple controls mean no more hunting for the right button mid-call. IT managers love the Poly Lens app for easy fleet management, while end users appreciate the 3-hour quick charge and all-day comfort.
